I have an ultrawebgrid and multiselect webdropdown is a templated column in that grid. It works fine when the page gets loaded first time but after postback the webdropdown gets disabled. Nothing happens on clicking the webdropdown.

I tried to create a sample site with webdropdown and a submit button in it. But even when this site runs, runtime script errors start coming.

Attached is the sample site.

Please help. We have a deliverable planned in 2 days.
